Block off the vacuum line to the distributor and put a timing light on it. Rotate the distributor to about 8 degrees BTDC at idle (750 rpm) and clamp it down tight. Reconnect the vacuum line and you should be good to go. You could experiment by increasing the advance in two degree increments until performance suffers and then back off 1 degree. You would rarely benefit from going beyond 14 degrees BTDC.
Should be on the side of distributor housing
It should have an electronic distributor. So no points to adjust. 0.18
That should work, but be remember you may be 180o off, so you mave have to adjust.
The air gap between the the tooth on the distributor shaft and the pick up coil should be .006. Be sure to use a brass feeler gage when setting the gap. Align blades good,And adjust to .008th.
Assuming that you know how to use a timing light to adjust timing: 1. Disconnect the electronic spark control at the distributor. 2. The timing should be 10 degrees btdc. Rotate the distributor to achieve the proper setting at the timing mark on the crankshaft.
How long should it approximately work a car distributor?
There is a brown wire below the glovebox this you unplug then you can turn your distributor after adj plug this wire back together! Engine should idle at 900 / 1100 rpm
It should be listed on a sticker near the fan shroud. My 1995 astro is supposed to be set at 0 degrees below top dead center. use a timing light to adjust the distributor accordingly. .
If the engine is EFI you must unplug the 4 wire plug behind the distributor before starting. Then rotate the distributor while using a timing light to the correct position. If the engine is NON EFI then you must unplug the vaccum line from the distributor and adjust the same way. You should plug the line off to avoid a high idle situation as well..
It should be 6 degrees before tdc, just make sure you disconnect the distributor's computer control wiring harness before you adjust, and check the timing with a timing gun.
The rotor inside the distributor should be pointing at the #1 spark plug.
A mechanic should complete the following on a tune-up. 1. Run an electrical test to insure adequate voltage from the battery and coil. 2. Check and adjust the fuel system and replace fuel and air filters. 3. Replace spark plugs, plug wires, distributor cap and rotor. 4. Check and adjust timing. After the procedure, he/she should give details on belt and hose conditions.
